I've been going through the archive of very hard puzzles and somehow I solved this one using just the basics. I figured that I must have made a mistake and got lucky so I did it a second time - and I solved it again by just using the basics! Could one of you double-check this puzzle for me? What am I missing? If you want, I can provide the sequence of steps that I used (I saved them the second time that I did it). Thanks, Don.

Don, every once in a while a VH sneaks through that can be solved with basics. This is probably not one of them. Whenever I solve one with basics and every other poster shows advanced moves, I get out the eraser and do it again. I've been burned and embarrassed by this issue a couple of times.

Thanks Marty! That's exactly what I'll do from now on! When I attempted to solve this for the 2nd time, I wrote a sequence number in each square (I thought) so I could easily recap how it was done. Now I notice that two squares are missing sequence numbers and I'm no longer able to deduce one of the next sequenced squares. I must have made the same stupid mistake twice! Sorry about that. I'll be more careful in the future! Thanks, Don.
